As any Eagles fan will tell you, hurries or as it is known in Philadelphia, "Mamula's" are not a stat that is all that important. Getting near the quarterback does not have a huge impact on NFL Quarterbacks. Sacks or hits on a quarterback matter.

In chess it's common to talk of "blunders". Even the best make them. Karpov made a famous blunder against Kasparov in the world championship. It happens. It's good of you to point it out, but don't make such a big deal out of it.

There does not seem to be any adjustment for usage. Guys don't rush the passer all the time, and some guys rush more often than others. Jordan, for example, was supposedly used in coverage quite a bit. If he or another guy is rushing on a smaller percentage of snaps than others, they will have more snaps per pressure even if they are more effective on a per rush basis.

He also says that Okefor received the least help but he had the equal highest number of average rushers so even if he wasn't getting productivity from his team mates they would have been making it harder to double team him.

College players play what? 12 games? Kinda disingenuous to say 25% of his sacks came against those three crap teams when those three teams represent 25% of the games he played. You'd expect a higher % to come against them if they were crap. So no, those three teams did NOT inflate his numbers.
